Abstract: We prove the maximal local regularity of weak solutions to the parabolic problem associated with the fractional Laplacian with homogeneous Dirichlet boundary conditions on an arbitrary bounded open set \Omega\subset\mathbb{R}^N Proofs combine classical abstract regularity results for parabolic equations with some new local regularity results for the associated elliptic problems.
